Question

Mention works where we use compressibility in our daily life?

Answer 1

Hint :In order to solve this question we must first know what compressibility is. Compressibility is the property of being reduced to a smaller space by inducing pressure. This property is said to be a consequence of porosity, and the change of bulk comes from the particles being brought closer together by applying pressure.

Complete Step By Step Answer:
The compressibility of fluid is basically a measure of the change in density which is produced in the fluids by a specific change in pressure. Gases are generally highly compressible compared to most liquids which have very low compressibility.
The fact that compressibility effects can have a large influence on the fluid flow. The study of these flows in which the changes in density and temperature are important is basically what is known as compressible fluid flow or the gas dynamics.
In our daily life, we use compressibility as
-Natural gas is compressed to liquid gas and stored in gas cylinders and used as fuel
-By compression of air, we can blow things like a balloon and at the same time collapse them.
-By compression of gases, we can pump air into the bicycle tire using a pump
-The air contained in car tires is made possible because gases are easily compressed

Note :
We must be careful to not get confused between compressibility and bulk modulus. Compressibility can be defined as the property of being reduced to a smaller space by applying pressure. Bulk modulus of a substance is defined as the ratio of infinitesimal pressure increase to a decrease of the volume. Bulk modulus is meaningful only for a fluid.
